[PATCH 1/2] arm64: dts: rockchip: enable NPU on rk3588-tiger

[Heiko Stuebner <heiko@sntech.de>]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

Enable the NPU cores and their mmus and wire up the supply-regulator.
The regulator itself was already defined, but it does not need to be
always on - the npu can control it.
